Businesses often use this type of accounting for the development of assets in the form of an accretion expense, or an increase in the present value as the asset draws closer to its final future value. It is also used in Mergers and Acquisitions (M&A) when discussing the earnings per share for the company using pro forma statements after the transaction takes place. In other words, these accounts for the synergies which are likely to be realized. In addition, it will feed directly into the combined entity’s bottom line. Accretion real estate is simply the development of land through the growth and development of land. This can be through the development of a shopping center or something simple like the growth of livestock through breeding.
